it amazes me that at some point people had to invent these things

14:45 I am still amazed at how coordinated you are doing three separate things at once: moving the pen at a constant speed and pressing two different buttons at different times in different combinations.

Having watched 5 videos previous to this, from transistor logic gates to the D latch, the use of the inverter delay in the edge detection circuit blew my mind to pieces. Biggest crossover event in cinematic history

You are every nerd's dream teacher

Using propagation delay of gates to build an edge detection circuit always reminds me of the quote, "when life gives u lemon, make lemonade out of it"

After 3 months of nonsense lectures at uni it take me about 20 minutes of watching your videos on latches and flip flops to completely understand it! Thank you so much for making these :D

man that breadboard time machine is crazy!

You are wonderful teacher , keep posting videos and make us educate, can you make a video on pull up and pull down resistors.

It feels like I learn more from these videos than from school, imagine that!

the edge detector is so clever. Never would have thought to exploit the delay in an inverter to create a quick pulse.

what amazes me is that Redstone is so similar to all this. The first flip flop I learned in bedrock edition is a d flip-flop

Amazing how you explain all these things step by step! I wish you were my teacher years ago. If they explained electronics the way like you do then my country would probably be on Mars already.

Very nice explanation of the flip-flop! I enjoyed learning about the delay which causes the true condition on the AND gate output. Very cool!

Thank you Ben for making these amazing set of videos available for anybody on the internet who just wishes to learn. I can't describe how much this means to me. THANK YOU.

Excellent! Everybody studying computer science must watch these video series. Thank you so much for your effort and time. Kindly think about to do more related to this topic. You are an extraordinary teacher.Thank you again Ben.

This is SUPER helpful. I'm taking a computer architecture class online and didn't understand the book. This cleared it up for me.

dude I kid you not I left computer engineering in favor of physics because my instructor couldn't explain this well enough! in 3 videos that took me about 30 minutes to watch I got it all!

This is a wonderful explanation of D flip flop. As a computer science student, I salute to you for this amazing video!

Man that was helpful AF, your explanation helped me to build a d flip-flop that transitions from 1 to 0 instead of 0 to 1, just replace the "And" gate with an "XNOR" gate

You make things so much simple with those circuits. Thank you so much.

Beautifully explained! Makes me shiver how it was explained so simply.

I just got an electronic kit and ive been binging these videos. Ben Eater is definitely to 50 people ever. like everyone else who's commented on his videos has said, everything just makes sense. he doesn't tend to explain things that don't need to be explained, and the things that do need to be explained are explained at the right speed, at the right time. i wish i could be in his class

This guy is so so so so so underrated.... I challenge no one is explaining this kinda topics currently on the you tube.

Your videos are great because they're bringing me back "To - The - Days". In my COMPE270 Logic Design Class, we did all our designs on LogicWorks software. Then we did the real circuits next semester in the COMPE470L Lab. I remember my fried fried the logic chip network and a few capacitors by accidentally connecting the network up to the 15v supply instead of the 5v supply. The electrolytic caps all smelled like baked bread! Oh the GooD times......

Wow, its amazing how easy it was to learn this because to a clear and able to show it using your circuts. If only you were my electrical professor.

thanks for your support towards my understanding Mr Ben

Love your all tutorial sir, Your way of teaching with practical approach is fabulous We would love to see more videos of electronic and communication. Thank you

Thank you for posting this! This is exactly what I need to further expound on a circuit I'm building. I will post a link to a video of the circuit if/when I get it functioning. Thank you.

VERY WELL DONE! Needed a little refresher during troubleshooting, and this video was perfect.

You are such an awesome teacher!!! I am so grateful for this video.

Excellent video. This guy knows exactly how to teach electronics. None better.

Another great video, 'events happening on the rising edge of the clock input/pulse' should make sense to usual programmers

This is the best thing I have ever seen. You should get an award or something for these videos.

Explain this is not easy, u do so clear. Thanks. I love Relays.

Gee - and I always thought that D-Latch and D-FLipFlop were identical and were just German/English terms. Thanks a lot!!! very well done video. I immediately corrected my simulator....

What a coordination! I'm pretty sure it would take me tens of tries to follow those signals at the same time XD

Rewatching these videos. Thanks Ben! It's probably not necessary, but the output could be put through a comparitor for a square pulse, though a Shmitdt trigger would be better, yet, I will try to use a an Op-amp to make a comparitor.

Thank you so much! I got covid and missed my lectures going over this, and your videos helped a lot. thank you

It's amazing to see it practically on breadboard

You're an excellent teacher, thank you very much for taking the time to make these videos.

these videos are a must-watch for anyone interested in electronics.

omg, thank you so much! It´s the night before my computer architecture exam and you saving me right now.

Thanks for explaining how the clock edges are detected, that was a mystery to me

Ben Eater is the best thank you so much and keep teaching please!

I love the fact that Ben's explaining how a major component in a 8-bit shift register works. ;)

You'rte a great teacher, Ben. I love the way you evolve from the SR to the D flip-flop by incrementally adding complexity to the circuit showing the evolution of design techniques.

You have no idea how helpful your videos to me thanks

Really appreciate these videos, our professors lectures are a bit hit or miss and some areas are difficult to understand. But your videos are excellent in quality!

Very nice explanation. It leaves no room for any doubt. Great work Sir.

This makes so much more sense than whatever my professor was trying to do...if i pass it is all due to your videos!

please make more and more videos that explain how a computer works internally. Your videos are really helping me in my MCA. Also make video on how different types of registers work.

Absolutely amazing. You make EE fun to learn. Thank you so much.

I feel like a little light went on there (no pun intended). I wish this had been explained to me this way in the past. Thank you, I really appreciate that. Great explanation.

superb content - thank you for making this so consumable for the next generation(s)

Does anybody else feel the excitement building as the pieces come together?

Thank you for the detail explanation. Keep up the great work !!

yet more proof that capacitors are magic and anyone who understands them is a wizard. I couldn't make any sense of that edge detector thing.

@12:12 the width of the Pulse is conceptual because that depends on the input of the gate receiving that pulse. So the width will span the horizontal level of the AND gate input, and the conceptual level starts at the trigger level and ends at it, then it rolls down after falling below that level.

the best explanation ever, congratulations!

Very cool, I have done my electrical, but I am very interested to learn electronics and your teaching is superb, so please do more basic Videos👍

Logisim broke when trying to make a DFF in this configuration, so I emulated the function by running 7-off, 1-on with the clock component at 8hz, could be 16 if I wanted to get even closer to instantaneous ticking. Anyway, thanks for the work you do! It's really helping me understand all this crazy stuff that goes on in computers and the embedded solutions (usually SOC) found in many devices we don't think of as computers

In my digital electronics class we were never taught that we needed an edge detector. I always wondered why we could change on the rise from 0 to 1 but not when clk was at 1.

You made a great job please don't stop share videos

your video was well prepared and has a best quality

T-flipflops are very useful for counters!

goddamn bro I learnt faster and better from your videos about latches and flip flops than the lectures of my drunk teacher xD thank you!

I think the inverter-delayed flip flop would also set off on a "downward" spike (that is input switching from 1 to 0). Not saying this would be a bad thing, possibly leading to doubling the actual clock frequency

You are the god of digital design much better tha my professor explains nothing on hour long classes lol

Excellent information about interesting circuits! I learned something new. My humble thanks.

Marvelous way of teaching....blessings friend!

that edge detector blows my mind.

Ben, thank you so much for this video. this video was exactly what I needed to begin building my "atomic clock" (WWVB Receiver/Decoder). I'm documenting my project here on KZfaq. I'd love for you to take a look and let me know what you think. Thanks again for sharing your knowledge thru all your great videos!

amazing very good studying digital electronics watching these support videos helps a lot in learning

wow and wow... your teaching skill is amazing sir

Love you ben(no homo). Just the way you explain things i can understand instantly without having to rewind most of the time. Your way of teaching needs to be studied

i literally hated electrical coz of the way it was taught in our uni, you just made it so damn interesting, tysm

@10:59 >>> this method of pulse creation is used in one of the security systems to detect the signature of the acousto-magnetic pulse signature - so by controlling the width of the generated pulses (via a variable cap controlled by an MCU) and taking iterated measurements (Assembly code is used as C code is not fast enough) the wave signature of the system can be detected and an alarm will be issued once the signature is matched to the pattern stored in the EEPROM of the chip. Digital-CAPs are available from vendors that can generate variable cap values through the SPI or UART port.

very good explanation. Thank you very much. Keep Sharing your knowledge

That and gate edge detector did work .. . And I had used just one

nice tutorial, starting to make sense!

The delay of NOT gate switching its state being used for edge detector reminds me of "It's not a bug, it's a feauture"

At 3:08 I nearly fell off my chair! Way to go, man!

Interesting note, the RC edge detector is effectively a high pass filter which lets the high frequency components of the square wave across. It could also be viewed as a circuit that takes the derivative of the square wave. At steady low state, the derivative is zero. When a rising edge hits, the rate of change is high but then quickly goes back to zero with the steady high state.

damn yo! better than the prof and the teaching assistant that i have. Subscribed!!!!

To detect a rising edge can we use an AND gate with one input the clock and the other input is the output of the AND gate itself but passed through a NOT gate. So when the clock is high the output of the AND gate will be HIGH only till it's complement which is a LOW reaches the other input of the AND gate effectively making the output of AND gate LOW again.

The turn on voltage of the individual gate you address is 'approximately" .5 of the max voltage of the IC. Which in it self is a time lag as, we all know there is no-such-as-thing-as instantaneous voltage change. A square wave is a clipped sign wave no matter how fast you clock it.

Wonderful sir! really amazing explanation!

Brilliant as always.

I was about to add my comments when I realized that the next guy had already said it. You are a very good teacher. You don't waste time; you build up your lessons carefully to get to main point of the class like a professor. I've seen several videos and they are very easy to watch and followed even when I'm completely lost or I'm completely aware of what is happening. I would like to start building up my digital electronics skills and need to buy all these ic's, protoboard and the such. I need to build up my bench and I wonder where do you think I should go to get all this peaces of parts, component and tools to follow you lectures. I need every thing like meter, scopes, parts, board, cables and the such.....I'm sure you know what I mean. I have nothing and need to start from zero. The only thing I have is my brains and my skills as a technician but I need every thing else. I want to build the 8 bit computer and I have other project that you may be able to assist me with. Thanks for you support and thank for these amazing lectures.

Reminds me of Doc's 1885 refrigerator in BTTF3. 😊

This is going from using my electrical engineering intuition to using my Redstone intuition and I’m not sure if that’s what is supposed to be happening?

10:00 I build it in a game with logic gates that have a speed of 40 "ticks" fancy word for hertz. When I press a button it takes 1 tick to activate the AND and to activate the NAND/NOR fed into AND then another 1 tick to deactivate AND because NAND changed to 0, which results in a 1 tick pulse and complete ignore afterwards unless you stop pressing the button and press it again. It's the only way to do that because the game doesn't have voltages or wires or current etc. It's either on or off, and connections are wireless (very convenient).

fantastic explanation thank you

really easy to edge my rising clock pulse to this video

I saw you addressed the racing issue in the JK-FF videos, so I just want to remark that D-FFs also have to be of the master-slave type to avoid the same problem. Also, please, put some decoupling capacitors next to ICs. 74LSs are more forgiving, but if you replace them with, let say, 74LVCs, or even 74HCs, decoupling capacitors are a must.

At 14:15 you show a sweet set of needle nose pliers, where can I get my hands on some? Thanks!

you are great man god bless you!!! i am big fan of you from india

You made my Day Ben!

If you could make packages of the components used for these lessons and start selling them online it would be amazing! Now when I wan to acquire them I have to buy a lot of them without actually even knowing how many I need in you next videos 😅

What is the point of the resistor there?
